Discovering mould in your car is one of those things that makes your stomach drop. Maybe you left the windows cracked during a rainstorm. Maybe there was a slow leak you didn't catch for a few weeks. Whatever the cause, one thing is certain: mould doesn't fix itself.

Where does car mould come from?
Mould needs two things to grow: moisture and organic material. Vehicles have both in abundance. A single water intrusion event — a leaking sunroof seal, a blocked drain, a forgotten wet towel on the back seat — can introduce enough moisture to kick off a mould problem within 24 to 48 hours.
Common hiding spots include under the seats, beneath floor mats, in the trunk, and deep inside the HVAC system. The tricky part? You often can't see it until it's already well-established.
Signs you might have a mould problem:
Why DIY usually falls short
Most people's first instinct is to grab some cleaning spray and go to town. And for small, surface-level mould, that can help. But vehicle mould is often hidden in places that are genuinely difficult to access — inside vents, under soaked padding, behind trim panels. Surface cleaning doesn't address what's growing underneath.
mould also spreads through spores, meaning disturbing it without the right equipment and containment can actually make things worse.
What actually works
Professional mould remediation for vehicles involves finding all the affected areas (not just the obvious ones), removing the mould at the source, and then treating the full interior to eliminate spores and prevent regrowth.
HealthyCar's mould removal process does exactly that — we locate, eliminate, and restore, with a written guarantee on the results.
If you've found mould in your car, the sooner you act, the better. mould doesn't wait around.
